Where's the best place to stay in Ibiza for three 17 year olds?

Have a look on the Ibiza Spotlight website for research but I suspect San Antonio will be what you are looking for. However, hotels do not take bookings where the whole party is under 18 so unless you take an over with you, you won't be able to make a booking. http://www.ibiza-spotlight.com/ As for spending money, well you'll need a lot because the clubs are expensive, ibiza is not a cheap holiday in general.

San Antonio is a good place to stay, you will be by the west end (the strip) and also eden and es paradise. If you fancy going to one of the bigger clubs you can just get a bus. Its a good base location.

san antonio bay area is great. the clubs are fantastic, take plenty of money.(about a grand each per week). i usually do, although i spend most of it on rubbish, and in the bars n clubs,,,oh yes,,and some food. look after yourselves. and have a great time.
